CUSHIONED SPRING-SEAT.

Application tiled October 16. 1916.

To all whom it may concern.'

Be it known that I, HENRY H. BURROWS, a citizen of the United States`and resident of Oshkosh. in the county of 'innebago and State ofWisconsin, have invented new and useful Improvements in CushionedSpring- Seats, of which the following is a description, reference beinghad to the accompanying drawings, which are a part. of thisspecification.

The invention relates to cushioned spring seats.

The invention is more particularly designed to provide a springcushioned seaty for use in automobiles.

The invention is further designed to provide a cushion seat in which aportion of the outer cushion casing is overlapped adjacent the uppermetal edge frame for the springs to forni a reinforcement extendingaround the upper edges of the seat.

s usually constructed the springs are held between the lower supportingframe structureand a fabric casing disposed upon the top of the springand extending down upon 'the sides and secured. to the lower frame, andthe cushion casing is laced on the top of the spring casing an extendsdown over the sides and securedto the lower frame. In constrtions ofthis kind it is usual to make the sides of the cushion casing of alength equal to the length of the sides of the spring casing an underthese conditions it frequently Ahappens when the upper cushion becomessides of the outer casing become longer than the sides of the springcasing and the spring casing has to take the whole pressure of thesprings. To obviate this diiculty the present construction rhas been'designed to make the sides of tflie spring casing of greater lengththan the sides of the stronger cushion casing so tha-t when the cushionis .compreed the pressure of the springs will at, all times be taken bythe cushion casing.

The invention further consists in the several features hereinafter setforth and more particularly defined by claims at. the conclusion hereof.

serial No. 125,779.

Fig. 3 is an enlarged detail of the edge construction.

In general the seat comprises a lower supporting frame, a plurality ofsprings 4 mounted on said frame, a fabric casing 1U for the springs anda cushion carrying casing.

The lower supporting frame comprises 'a rectangular wooden framesec-tion 5 and transversely extending metal channel spring supports 6.These channel supports are secured to opposite sides of t-lie framesection 5 and are disposed with their flat surfaces uppermost. At pointswhere it. is desired to secure the springs 4 the metal supports arepunched out to form tongues 7 which are ent over to clamp the lower ends8 of the spi-ings between them and the fiatace of the support. 6. All ofthe springs are secured to the' supports 6 in this'nianner and toprovide for greater resiliency and cushioning effect the supports 6 arebent downwardly from the pointat which they are attached t0 the framesection 5 to form transversely eX- tending portions 9 disposed below theframe section 1 so that long springs may be usedk in the intermediateportion of the seat.

The springs 4 are interconnected at. their top' by means of clips l1 andthe outer springs are connected to a top marginal rod frame 12 by clips13.

The fabric spring casing 10 for the springs consists of a top portion 14disposed u on the top of the, springs 4 and extendping around the rodframe 12 and thence downwardly formingsides 15 which are secured attheir lower edges to the wood frame 5. The casing 10 is secured to themarginal rod sectional view 4frame 12 by stitching 14 passing throughthe top and sides of said casing.

The cushion carrying casing consists of an outer fabric consisting of atop portion 16, the edges of which extend over the frame 12, as shown inFig. 2. and are stitched to a marginal edge ortion 17 disposed below theplane of 'the ro 12 and in which cord beading 18 is disposed, an outerfabric side portion 19 being also stitched to the portions 16 and 1T andextending over the frame 5 and secured thereto, and an inner fabricportion and pa-ddin 2O being interposed between the inner an outerfabric port-ions and lying upon the top portion 14 of the spring casying 10.

loo

lslightly thus relieving t carrying casing consists of a piece of fabric21 which has altop portion 22 extending for a short distance overthe topportion 14 of the casing 10 and thence extending downwardly adjacentthe'side 15 -of the casing 10 to forni a siding 23 which is folded overat its bottom edgevto form the fabric siding 24: which-is interposedbetwen the sides 19 and 23 and is secured at its bottom edge to theframe 5 and at its upper edge is folded over several times to form anoverlapping top 25 adapted to be disposed between the tops 16 and 21adjacent the marginal rod frame 12 to form a reinforced edge. The fabrictop 16, the marginal edge 17, side portions 19, 24 and 23 are allsecured together b v stitching 26. From Fig. 3 of the drawing it will beapparent that the portions 21 and 23 which form the inside layer of thecushion casing pass directly over the casing l() adjacent'the rod frame12 with the result that when the fabric 21 is secured at its lower endto the frame 5 there will be a straight pull on the spring frame and theouter fabric portion of the cushion casing willbe relieved of strain.Furthermore the overlapped top 25 prevents any wear from the wirethrough the front facing of the cushion casing and-the stitching 26 ismade below the marginal edge to prevent wearl These features inherent inthe construction shown relieve the outer facing of the cushion of wearand strain and the overlapped top 25 at the marginal edge prevents thecushion from sag 'ng because the padding is firmly held in p ace.

In order that the sides 15 of the spring casing 10 may be relieved ofpressure as the outer cushion casing stretchea'the length of the sides4of the cushion casing are made somewhat less than the length of the sides 15 so that said sides 15 will be slack as shown in Fig. 2.

The top portions` 22 extend inwardly for a short distance as shown inFig. 3 and are connected together by cross-lacing 27,' the padding 20beingdisposed between the lac-,V

ing 27 and the outer fabric top 15 of the seat In the manufacture ofseats of the construction described the springs .are secured to thelower frame, the'spring casing A10 brought down over the springs andsecured to the lower frame and' then the whole cushion-carrying casingis placed over the spring casing and the bottom edges are drawn downtightly, compressing the springs ev spring caslng of tension, and tackedto the wood frame.

With the construction above described the overlapped top 25 forms -areinforced edge,

reinforces the seat' adjacent the'Y marginal frame 12 and its edgeswhile the slack siding 15 of the spring casing takes the pressure off ofit and allows the stronger re-inforced outer casing to maintain thesprings in proper position on the frame.

The invention thus exemplifies a simple and efficient cushioned springseat construction. l

What I claim as my invention is:

1. In a spring seat, the combination, with a spring cushion includingsprings and an upper marginal frame to which the marginal springs aresecured., of a cushion comprising a pad and an inclosing fabric casingfor the pad, the pad being arranged behind the marlglnal edge of theupper frame, the marginal edges of said fabric casing having overlappedfabric portions held in place against said upper marginal frame toprotect the marginal edge of the cushion against wear and hold the padin place and prevent its Working out over the outer edge o'f thecushion.

2. In a spring seat, the combination, with a frame, a plurality ofsprings mounted on said frame, an upper marginal frame for the sprino's,a padded cushion comprising an outer fabric facing, an inner fabric4facing secured to the outer fabric facing adjacent the marginal frame,a padded portion interposed between said outer and inner facings abovethe springs and tapering inwardly from theouter edge of the cushion, andan overlapped portion interposed between the outer and inner facingsadjacent to the marginal frame to protect the outer facing from wear andhold the padded portion in place.

3. In a. spring seat, the combination of a lower frame, a plurality' ofsprings mountedd on said frame, a marglnal edge frame secured to thetops of the marginal springs, a fabric casing extending over the tops ofthe springs andhaving its sides secured to they lower frame, and acushion carrying casing fitting over the fabric spring casin and havingits sides secured to said lower` rame, the sides of the cushion casingbeing of less length than the sides of the spring casing to provide aslack in the sides of the spring casing, said cushion carrying casinghavin an overlapped fabric portion dlspos against the marginal edgeframe anda padded Aportion` within the. casing extend# ing up to theouter edge of the seat and held against working out over the 'edges bysaid overlapped fabric portion.

In testimony whereof I aix my signature.
